HosE-cotrr-Lind GASKET, Y

To all 'whom it may concern."

Be itknown that I, EGBERT H. GOLD, a

cago, inthe county of Cook, State of Illinois, have invented certain new and useful Y train pipes on railway carsya'nd thelobjectV` of the invention is to provide an improvement. in the gaskets used in couplingsof' `this sort.v These gaskets vhave Vordinarily beeninade of a rubber-like composition'such as a mlxture of rubber and plumbago orof other'similar plastic material Which-1s relatively hard butv slightly compressibleand capable of expanding under the temperature f of steam.' Gasketsof this sort are quite eX- pensive andv experience hasshown thatrthey are easily mutilated, particularly 'at the face ofv thelgasket by the rocking of one cou' pler on thebtherpin a Sewalllor gravity -typeo'f coupler, and'lby .the fpressurel exare locked tog'ether by some1 :Wedging device. as is 4'the'i'case- With couplers of certain Well knoivn. types. Myinvention provides a thin metal' armoring or facing to 'cover the face of the gasket Ytvhich Will pro- .tcct a compos1t1on`= gasket bodyjof the char- -acter above referredto,l against these destructive pressures'w'hile permitting the expansion-of the gasket Where suchexpansion is necessary, inV order to give a steam tight joint. YPreferably the armoring is made so hat it-can be readily attached to and detached from the gasket body, as this may be desirable in some cases. 1

The invention is illustrated, in certain preferred embodiments, in the accompanying drawings, wherein'- Y Fig. 1`is a cross sectional view of apair of mating couplers of the safety type pro-` vided with the usual composition .gaskets armored in accordance With my invention.

In accordance Withfmy irl-. *vention the face of thisgasket'V is covered '.-vvithx-a thinmetalfacing 14 lpreferably. made Ofcpp'er. or brass.

The armoring permits the gasketto expand under the relatively highv temperature of the steam passing through the coupling, this expanf sion being necessary in a ycoupling of this sort in order to insure a ysteam-tight joint.

Fig. 3 illustrates an application o'f'jth'e armoring to a gasket of the ksort used in a F ig.' 5 is a sectional view on line 5-,5 ofV Chicago type coupler," thev composition l body being indicated at 21 and the metal-fr,

facing member at 22. n .v

The Chicago type oflcoupler, this type ing member 23 with an eccentric conical end 24 adaptedto bearagainst the arm 25 ofthe mating coupler (Figsf/, 5 and 6), the locking member being located ina bore formed being also Well known, has a revoluble lock-l soL in the coupler head 26. In these figures the mating coupler is shown as a safety type coupler and designated 27, arm 25 just referred to being a part ofthis coupler. The

locking member 23 may be driven home soV hard as to produce considerable pressure between the gaskets. The danger that this pressure will mutilate a plastic composition gasket is enhanced if one of the. couplersv is provided with a metal gasket member such as is shown in Figs. 4 and 5, in connection With the Chicago coupler. This metal gasket member, Which is not claimed herein,

being the invention of Edward N. Roth and described and claimed in application for` United States patent filed March 18, 1919, Serial No. 283,291, consists of a steel ring 28, to a certain extent resilient but quite stid, with a soft metal covering 29 provided with fingers 30 for engaging the ring either to the coupler or to the ordinary coupler gasket 3l, the latter arrangement being shown in the drawings. bviously a gasket member of this type, if thrust with force against the ordinary plastic composition gasket, would be likely to injure the face of the latter. By

armoring the other gasket lin the manner previously described this danger is eliminated.
